Llana [10]

Answer:

(a) Equations for both

y = 500 + 12x --- lifeguard

y = 15x --- camp counselor

(b) Total pay for 5 days

Lifeguard pays $800

Camp counselor pays $375

(c) Which pays more

Lifeguard job pays more

Step-by-step explanation:

Let

x \to hours

y \to total\ pay

Given

Lifeguard job

Signing\ bonus = \$500

Rate = \$12/hr

Camp counselor job

Signing\ bonus =\$0

Rate = \$15/hr

Solving (a): The equation for both

The total pay for each job is calculated as:

Total Pay = Signing Bonus + Rate * Hours

So, we have:

Lifeguard

y = 500 + 12*x

y = 500 + 12x

Camp counselor

y = 0 + 15 * x

y = 15x

Solving (b): Total pay for 5 days

First, we calculate the total hours worked in 5 days

x = 5hrs/day * 5days

x = 25hrs

So, the pay for each is:

y = 500 + 12x

y =500 + 12*25

y =800 --- Lifeguard

y = 15x

y = 15 * 25

y = 375 --- camp counselor

Solving (c): Which job pays more

By comparing the solution in (b)

800 > 375

<em>Hence, lifeguard job pays more</em>

WILL GIVE 10 POINTS Leona was using an eyedropper to place droplets in a small container.
il63 [147K]

Answer:

A. milliliters     B. 8 fluid ounces

Step-by-step explanation:

An eyedropper is very small and can only hold a small amount.  You can eliminate 2 from the start: millimeter and meter.  These two are use for measuring distance not volume.  ex.) I walked 2 meters.  A liter is too big for an eyedropper.  ex.) 1 liter of soda.

A glass full of juice would be 8 fuild ounces because a glass is basically a cup.  A 8 gallons is too big, and a 8 tablespoons is too small.  ex.) gallon of milk and tablespoon of sugar.  8 cups is too big because a glass is about 1 cup.  8 fluid ounces = 1 cup

Solving with percent and percent problems
Marysya12 [62]
Well, if 0.4% was defected, then 99.6% of the parts are good, because 100-0.4 is 99.6. Multiply 99.6% with 54650, and you get 54431.4. You should round down, because you can't have parts of parts. So, 54431 parts were good.
